Claims. (01. 292-218) This invention relates to improvements in door fasteners of the rotary bar actuated type for hinged doors, and more particularly to means for holding the rotary bar locked against rotation in door opening direction when the door has been forced to closed position by the fastener.

One object of the invention is to provide simple and efficient means for locking the rotary operating bar of a door fastener against rotation in door opening direction to hold the doors tightly closed, comprising a swinging operating lever connected to the bar for rotating the same, wherein the operating lever is provided with a locking extension or projection and is displaceable lengthwise of the bar to bring the locking extension thereof into position to block rotation of the bar by engagement with the outer side of the door.

Other objects of the invention will more clearly appear from the description and claims hereinafter following.

In the accompanying drawings forming a part of this specification, Figure 1 is an elevational view of a portion 01 one of the side walls of a railway car provided with hinged doors, illustrating my improved mechanism in connection therewith. Figure 2 is a horizontal sectional view, corresponding substantially to the line 22 of Figure 1. Figure 3 is a view similar to Figure 1, on an enlarged scale, showing the construction at the meeting edges of the doors, the top and bottom portions of the doors being broken away. Figure 4 is a horizontal sectional view, corresponding substantially to the line 44 of Figure 3, illustrating the operating handle lever in full lines in a position corresponding to that shown in Figure 3, and also indicating in dotted lines the position of the same after the bar has been partly rotated by the lever. Figure 5 is a broken View, similar to Figure 4, showing the operating lever swung through an arc of 180 degrees and the right hand door swung to position at right angles to the car wall. Figure 6 is a broken view, similar to Figure 3, illustrating another embodiment of the invention. Figure 7 is a horizontal sectional view on the line l'! of Figure 6.

In said drawings, Ill indicates the side wall of a railway car, which is provided with the usual door opening ll, closed by a pair of hinged doors [2 and I3, swingingly supported by hinges i l-l4. As is common practice, the door l2, which is that first closed, is overlapped by the door l3, and held in closed position by the latter. The door [3 carries the fastener mechanism which is of the well-known rotary bar type, comprising a vertically disposed, rotary operating bar I5, having keeper engaging crank members i$l6 at the top and bottom ends cooperating with the usual slotted keepers |1-|| for forcing the door l3open or closed. The operatingbar I5 is rotatably supported by top, bottom, and intermediate'bearing'brackets l8, l9, and '20, fixed to the door l3, and thekeepers H and I! are fixed to the side wall iii of the car above and below the door opening H.

My improved mechanism, as shown in the embo'diment Of the invention illustrated in Figures 1 to 4, inclusive, comprises broadly an operating handle lever A for rotating the bar l5 of the door fastener, operatively connected to the bar for sliding movement lengthwise of the same and having a locking arm or lugthereon adapted to be positioned by displacement of said lever in vertical direction on. the bar to block rotation of the latter in door opening direction.-

The operating-handle lever A, which is in the form of a bar, has a hand "grip portion 2! at its outer end and 'a cylindrical sleevelike head 22 at its inner end. The sleevelike head 22 serves to mount the lever onthe bar 15, which,

as shown, is of cylindrical, transverse section and has a sliding fit within the opening of the sleeve. A pin 23 extending diametrically through the sleeve and through a lengthwise extending slot 2-4 in the bar serves to secure the lever A to the bar for rotating the latter. 'The head 22 of the lever A carries a locking finger' or lug 25' at the side thereof opposite to that which carries the operating handle lever portion 2'! The lug 25 is formed integral with the sleeve, that'is, it is rigid with the operating handle lever. As shown in Figures 2 amid, the finger or lug 25 is offset inwardly toward the door it with respect to the planeof the handgrip portion 2| of the lever so as to engage the outer surface of thedoor I3 and. block the lever Aand the bar 15 against rotation in' contraclockwise direction, as Viewed in Figure 2, when the partsare in'the positions shown in Figures. 1 and '2. To provide" ample support for the operating handle lever" in this last named position, the bar is" preferably provided with a shelf 26 in the form of acollar' clearance for swinging movement of the lug 25 of the lever'A when the latter is displaced up wardly on the'bar to'an extent to register the lu'g with said recess. As will be obvious, the slot 24 of the bar i5 is made of-suflicient length to permit the required amount of upward sliding movementof the lever on the bar.

The operation of the improved mechanism shown in Figures 1 to 4, inclusive, is as follows: Assuming the doors to be in their closed position, with the lever A locked against rotation in door 3 opening direction, as shown in Figures land 2, by engagerlifeiit of thflugzfi of th leverawith the. outer side of the dodr Iii-the attendant' first slid'es the lever upwardly on the bar to align the same with the pocket 21, thereby unlocking the lever igi the operation is substantially theireverse' of that just described, the lever A, while horizontally aligned with the pocket or recess 21, heing'swungin clockwise direction to cam the door shut thrbughirotatlon iof the 'baiz I5, andothenebei-ngxt droppedito theipositiontshownin Figure: iet'o lock 1' the 'le'verand'b'ar against rotation in door-opening: directions;
